I got that Duncan also.I got one small frag of it,now there are about 6 polyps now around the main one.It looks like it's will be a hard coral to frag as of now?I remember in the Veron book of corals had one,but this one had branching type.Which could be a different type of Duncan.But this guy is very dense yet,it was fragged some how?So only time will tell.Keep feeding it,and polyps will pop out around it's lower base.They say it's a close to the Elegance coral,they do look kinda of close.Mine also came from Phishy....a different type of coral for sure.
